T 0 all 10 ham it may concern:

Be it known that I, JOHN A. STEVENS, a citizen of the United States of America, and resident of the .city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Drop-Leaf Calendars, of which the following is a full, clear, and exact description.

This invention relates to improvements in calendars, and the object of the invention is to provide a calendar which may be manufactured, sold and distributed at a minimum cost.

A further object is to provide a calendar in which it is not necessary to tear-01f the sheets of the months as they lapse so that the sheets may be retained, without inconvenience, for reference.

At the present time calendars and particularly advertising calendars are composed of a series of sheets usually one for each month which are bound together at their upper edges. The pad thus formed may have advertisements on each sheet or may be attached to a larger sheet containing advertising matter which shows above the calendar pad and by which the calendar is suspended. These calendars are usually packed for distribution in paper tubes. The cost of distribution is heavy owing to the cost of rolling the calendars and placing them in tubes, the cost of the tubes and the ostage on the tubes if delivered by mail. gVhen the calendar is in use the sheet representing each month is usually torn-off at the end of the month and is therefore, not available for reference, although in some instances it may be folded to the back of the calendar.

According to this invention the sheets of the calendar are secured to a backing or cover intermediate their upper and lower edges and the cover is provided with a flap. The calendar sheets and cover are folded at their line of attachment and the flap folded over the edges and secured by any suitable means. The address and postage may be placed on the exposed surface of the cover and the calendar distributed by mail or by hand in flat condition. The stitching and folding may bedone by machinery at very small cost. It will thus be seen that the cost of tubes and the cost of inserting calendars in tubes is eliminated. Obviously the tubes weigh much more than the cover of the calendar and there is therefore a considerable saving in posta e if large numbers of calendars are maile calendars placed in envelops or wrappers for distribution the cost of insertin is el1minated in each case and in the case o packin 1n envelops the cost of the envelop is eliminated.

In the drawings which illustrate the invent1on;--

Figure 1 is a plan view of the calendar cover showing the upper surface.

Fig. 2 is a plan view of a calendar sheet showing the front surface.

Fig. 3 is a plan view of folded for distribution. Fig. 4 is a plan view of the calendar as 1n use.

Fig. 5 is a vertical, sectional view on the line 5-5, Fig. 8.

Fig. 6 is a section on the line 6-6, Fig. 4.

Referring more particularly to the draw ings, 1'1 designates the cover or back of a calendar comprising portions 12 and 13 of substantially equal size connected at a fold line 14 and provided at one edge, preferably the calendar As compared with parallel with the fold line, with a flap 15. a

The flap 15 and the portions 12 and 13 are provided with alined apertures 16 which may be reinforced if desired and which are so disposed as to come into register with one another when the sheet is folded as shown in Fig. 5. Que part of the cover, for example the part 13, may be provided with lines 17 for the inscription of an address. The inner surface of this cover sheet may be plain or may be inscribed in the part like are arranged in the manner well known to printers so that when the sheets are superposed and connected at the crease lines the advertising or other matter for each month and the calendar for that month will come together. For example, the sheet illustrated contains on one side the advertisement for November and the February calendar and on the opposite side (not shown) the advertisement for January and the December calendar. It will thus be seen that six sheets will provide twelve monthly calendars and 12 monthly advertisements or the like. Each sheet is provided adjacent each shorter edge with an aperture 23, these apertures being located to register with the cover apertures 16. The inner surface of the cover may be used for advertising or for yearly calendars or for calendars of the last and first months of the past and succeeding years respectively. The calendar sheets are arranged in a pile upon the inner surface of the cover, the creases of all sheets and the cover being in register and any suitable fastening means 24 inserted to secure the sheets to the cover. By passing the calendars through a folding machine the sheets and. cover are folded on the connection line and the flap is folded down to cover the edges of the sheets and cover. A removable fastening device 25 may be inserted automaticall or by hand through the alined apertures o the cover, calendar sheets and cover flap to secure the whole in folded form. The calen- 'dars are now ready for distribution and require no further treatment beyond addressing and mailing if this is desired.

The recipient of the calendar removes the fastening 25 and releases the portion 12 of the cover and one half of the first sheet which drops to the position shown in Fig. 4. The apertures in the remaining sheet edges, in the cover portion 13 and in the flap are still in alinement and serve for the passage of a nail or the like from which the calendar may hang. At the end of each month the user disengages the upper leaf from the support and allows it to drop into position over the calendar for the precedin month, thus concealing the previous month s calendar and displaying the current month. Obviously it is not necessar to remove any calendar sheet so that'at ail times the calendarrepresents a complete year.

The advantages ofthis arrangement to my hand.

I both the distributer and user of the calendar are apparent from the foregoing description. The cost of producing the calendar is little if an greater than the cost of producing an or inary twelve-sheet calendar. The calendar is virtually packed for distribution in the rocess of making and no additional packlng is necessary, thus eliminating the cost of packing operations and packing material. In the event of mail distribution the postage on the packing material is saved. The user obtains a calendar which .may be chan ed from month to month with no greater di culty than the ordinary tear-off sheet calendar and has, in addition, a calendar which remains complete throughout the year.

Having thus described my invention, what I claim is A calendar cbmprising a backing in the form of a mailing folder conslsting of a sheet having a central transverse line of fold provided at one end with a single aperture and at the opposite end with a plurality of apertures located close together and 111 alinement with one another and with the first mentioned aperture, and a series of calendar sheets attached to said backing at the line of fold and foldable therewith, said sheets being provided with an aperture at each end thereof, the v arrangement bein such that the various apertures in the backing and calendar sheets are capable of being brought into registration. with one another to provide a transverse passage through which a fastening or su'pportin member may be inserted according to w ether the device is to be sent through the mails or is to be suspended upon the wall in the use thereof.

In witness whereof I have hereunto set JOHN A. STEVENS.
